6.5 quake on Richter scale aftershock in Aceh

Indonesia's Disaster Mitigation Agency on Wednesday reported a 6.5 magnitude earthquake on the Richter scale following an 8.7 magnitude temblor off the coast of the country's Aceh province, triggering a tsunami watch for the whole Indian Ocean.

Indonesia's disaster mitigation agency is sending a rescue team to Aceh.

"The quake was felt very strongly. Electricity is down, there's traffic jams to access higher ground. Sirens and Koran recitals from mosques are everywhere," said Sutopo, spokesman for Indonesia's disaster mitigation agency.
